Max Size: Up to 18 inches Water Parameters: pH 6.0-7.5, temperature 75-82°F, hardness 3-12 dGH Diet: Carnivorous – primarily feeds on live or frozen foods such as bloodworms, brine shrimp, and small fish. May accept high-quality sinking pellets and gel-based foods over time. Temperament: Generally peaceful but can be territorial with other knifefish. Best kept in a large, well-structured tank with ample hiding spaces. Tank Setup: Requires a spacious aquarium with plenty of driftwood, caves, and plants for shelter. A soft sandy substrate is ideal, and subdued lighting helps mimic their nocturnal nature. Compatibility: Best suited for tanks with peaceful, similarly sized fish such as larger tetras, peaceful cichlids, and gouramis. Avoid highly aggressive species or fin-nipping fish. Behavior: Nocturnal and shy, often hiding during the day and becoming active at night. Uses electrical signals to navigate and detect prey in low-light conditions. Fun Fact: Like other knifefish, the Marbled Ghost Knifefish generates weak electric fields to sense its surroundings, making it one of the more unique freshwater fish in the aquarium hobby.
